Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504056, here are decompositions:

5 + 31504051 = 31504056
19 + 31504037 = 31504056
43 + 31504013 = 31504056
79 + 31503977 = 31504056
83 + 31503973 = 31504056
127 + 31503929 = 31504056
139 + 31503917 = 31504056
173 + 31503883 = 31504056

Showing the first eight; more decompositions exist.
